  • AOMedia Forms AV1 Software Working Group Using Intel's SVT-AV1

    The Alliance for Open Media (AOMedia) today announced the formation of a Software Implementation Working Group (SIWG) to bring AV1 video support to more platforms by leveraging Intel's open-source SVT-AV1 implementation.

    This AOMedia working group is working to bring AV1 encoder support to more platforms and the group is being chaired by representatives from Facebook, Tencent, and Intel.

  • Paving the way for high bitrate video streaming with GStreamer's RTP elements

    RTP is the dominant protocol for low latency audio and video transport. It sits at the core of many systems used in a wide array of industries, from WebRTC, to SIP (IP telephony), and from RTSP (security cameras) to RIST and SMPTE ST 2022 (broadcast TV backend).

    Being a flexible, Open Source framework, GStreamer is used in a variety of applications. Its RTP stack has been battle tested in multiple use-cases across all of the aforementioned industries, giving it the distinct advantage of being able to apply optimisations from one use case to another. Without a doubt, GStreamer has one of the most mature and complete RTP stacks available.

  • NVIDIA Linux Driver Preparing To Drop SLI AA/AFR/SFR Support

    NVIDIA is preparing to remove support for multi-GPU modes of AA (anti-aliasing), AFR (alternate frame rendering), and SFR (split frame rendering) from the Linux driver in the near future.

    NVIDIA has updated their deprecation schedule today to reflect that the current NVIDIA 450.xx driver series is the last branch supporting SLI AA/AFR/SFR modes. NVIDIA 450 is the current stable Linux driver series this summer while soon should be succeeded by a new series in ushering in the upcoming GeForce 3000 series support.

  • Vallium: a *software* swrast vulkan layer FAQ

    I had some requirements for writing a vulkan software rasterizer within the Mesa project. I took some time to look at the options and realised that just writing a vulkan layer on top of gallium's llvmpipe would be a good answer for this problem. However in doing so I knew people would ask why this wouldn't work for a hardware driver.

  • Why VALLIUM Is Just For Software-Based Vulkan & Not GPU Hardware Drivers

    Merged into Mesa 20.3 earlier this week was VALLIUM as a Vulkan front-end to Gallium3D with an explicit focus to serve as a CPU/software-based Vulkan implementation and relying upon the Gallium/LLVMpipe infrastructure. But with VALLIUM being a Gallium3D front-end, some have wondered whether this could allow Vulkan to magically work with existing Gallium3D hardware drivers or even to run Vulkan on GPUs not natively supported by Vulkan.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
